:open_book: `Docs`: Improve `Commands` part

[iyear]

What should be changed?

We currently support many commands, but the docs only describes some of them. Better docs would help users to use dtm faster.

Submit new issues as subtasks to improve our docs! 👏

Requirements: Machine translation can be used, but the mechanism of dtm must be understood and the translation results must be corrected manually as necessary. Doc translation is important and difficult, so please take it seriously.

Note: Please start translating after the issue has been assigned! This helps us keep track of the documentation work. PR without corresponding assignee may be closed directly.

Missing docs:

• show.md & show.zh.md
• list.md & list.zh.md
• apply.zh.md
• autocomplete.zh.md
• delete.zh.md
• destroy.zh.md
• init.zh.md
• verify.zh.md
